Title: An electric switch
Inventor: BOSCH HENDRIK ADOLF
IPC: H01H71/52
Filed: 1992-12-17
Abstract: Electric circuit breaker or load switch, comprising a housing (21), at least one pair of contacts consisting of a fixed contact (23) and a movable contact (24) which can assume a first and second position relative to the fixed contact (23). A spring system, made up of a rigid arm (33) and a leaf spring (30), which leaf spring (30) is hinged by one end (32) to the arm (33), such that an arm-leaf spring assembly in the form of a toggle mechanism with a first (31) and second end (34) is formed. The first end (31) of this toggle mechanism is hinged to a movably supported element (25) having the movable contact (24), and the second end (34) is disposed hingedly supported at a distance from and opposite the fixed contact (23). Control means (37, 40) act upon the arm-leaf spring assembly for taking the contacts (23, 24) into the first and/or second position, in which the leaf spring (30) is released or tensioned, and latching means (45) are provided for locking the contacts (23, 24) in the first and/or second position. The rotatably disposed second end (34) of the arm-leaf spring assembly, the fixed contact (23) and the movable element (25) are positioned in such a manner relative to each other that the arm-leaf spring assembly both in the first and in the second position of the contacts (23, 24) assumes a relatively deflected position with respect to the situation in which the arm (33) and leaf spring (30) lie virtually in line with each other, with the result that the connection length of the switch is effectively reduced. <IMAGE>

Title: Fluid diffuser for gases and liquids
Inventor: WEBER RICHARD B
IPC: C02F1/24
Filed: 1984-01-20
Granted: 1986-04-23
Abstract: A fluid diffuser for dispersing a gas or liquid into a body of receiving liquid in which it is immersed. The diffuser includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and an annular ring positioned adjacent the outer perimeter of the disk-like member. At least one of the top and bottom walls of the annular ring is porous. These top and bottom walls define a fluid plenum, into which gas or liquid under pressure is introduced to be emitted from the plenum as small, nascent fluid spheroids on the surface of the annular ring. The boundary layer flow from rotation of the disk-like member within the body of receiving liquid shears fine gas bubbles or liquid particles from the foraminous surface or surfaces of the annular ring. The annular ring may be fixed, or rotatable in the opposite annular direction from the rotation of the disk. Impeller blades may be mounted on the top and/or bottom surfaces of the rotatable disk. The fluid diffuser is disclosed immersed in a flotation tank with a system of baffles to define a mixing zone at the bottom of the tank and a flotation zone at the top of the tank. Preferred embodiments of the diffuser include features to improve the mixing as well as diffusing action of the device.

Patent HU-214228-B (HU)
Title: An encryption method for providing data security
Inventor: MITTENTHAL LOTHROP
IPC: H04L9/06
Filed: 1992-08-04
Abstract: Methods and apparatus for nonlinearizing modulo 2 addition based encryption by block substitution techniques which allows use of the substitution scheme with relatively simple hardware and yet makes cryptanalysis more difficult. The basic block substitution, a one to one mapping of n bit binary numbers onto themselves, is based on the fact that certain permutations of the n bit binary numbers define a block substitution by modulo 2 addition of one permuted set of numbers to another, and that a subset of these define equations having an additive relationship when viewed as vectors. This allows the simple changing of the transformation on a frequent basis. Then the equations are nonlinearized, also in an orderly and readily variable manner, so that the remainder of the set equations may no longer be generated from a limited subset of the equations. Various properties of the transformations and methods of using the same are disclosed.

Title: Tools to seal sliding doors
Inventor: CAMPRI ITALO
IPC: E06B/
Filed: 1989-02-13
Granted: 1992-05-18
Abstract: The present invention concerns some peculiar tools to seal sliding doors.Thanks to said proceedings, sliding doors, which hang on sliding bogies through articulated plates that are parallel to the sliding track, can oscillate transversally until they touch the seal. Said seal leans from the box that delimits the access on three sides.The transversal motion of the door, which can be carried out once it is closed, is actuated by two couples of bars, which coming out from the horizontal edges of the door, enter the respective seats, which must be adequately shaped.Each couple of bar is linked through two rods to one of the gears that are bound to a driving chain, said chain being actuated in both directions by the handle coupled with one of said gears.The fact that the inferior bars come out of the edge of the door makes a horizontal bar descend, said bar being provided with a seal that completes the hermetic closure of the whole perimeter of the access, once it is pressed against the ground.

Title: A medical device shaped like a shoe or a boot, with a compression chamber put into action by the walking of the user specifically for treating oedema of the feet and legs.
Inventor: RACO GIUSEPPE

Filed: 1990-05-16
Granted: 1993-09-03
Abstract: This device shaped like a shoe or boot, equipped with at least one space (5) used for a fluid, that binds the area of the foot and/or leg that needs to be treated and the internal wall (3) that is sufficiently elastic. This space is connected to one or more containers (12) of the appropriate volume, placed under the foot of the patient, in correspondence to the heel and/or sole. Full of fluid and oriented downward with at least on flexible and/o moveable wall, so that during the patients walk, the pressure that they rhythmically exert on the container (s), bring a proportional increase in the pressure in the said space. This causes a compression message from the bottom up on the part of the foot and/or leg in which the blood and lymphatic circulation needs to be reactivated.
